Analytical mean-field approach to the phase-diagram of ultracold bosons in optical superlattices
P. Buonsante, V. Penna, A. Vezzani
We report a multiple-site mean-field analysis of the zero-temperature phase diagram for ultracold bosons in realistic optical superlattices. The system of interacting bosons is des…

Phase Diagram for Ultracold Bosons in Optical Lattices and Superlattices
Pierfrancesco Buonsante, Alessandro Vezzani
We present an analytic description of the finite-temperature phase diagram of the Bose-Hubbard model, successfully describing the physics of cold bosonic atoms trapped in optical l…
